Step-by-step explanation:
If you're completing the square the answer is in the image.
expression
x^2 + 5x - 5=ax^2+bx+c
a=1, b=5, c=-5, and you can solve it that way.
The square root 5 is irrational because a square root of a positive number is either an integer or irrational number. Therefore it is irrational.
Answer:
Suppose 3 consecutive integers are X-1,X,X+1
Step-by-step explanation:
Sum = X-1+X+X+1= -78
3X=-78
X= -78/3
X= -26
3 consecutive integers are, -27, -26,-25.
smallest integer is -27
There are 125 refrigerators in total.
Explanation:
